Specification of Letters Patent.

Application filed October 15, 190?. Serial No. 397,53.

To all whom it may concern:

Be it known that I, HowAnn E. CoFFIN, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements inLever-Locking Means, of which the following is a specifica therein tothe accompanying drawings.

The invention relates to controlling mechanism for motor vehicles, andhas particular rlference to the locking means for holding thecontrolling lever in different positions of adjustment. i, Y

' The invention consists in the novel construction, arran ement andcombination of parts as hereinafter set forth. y

1n the drawings-Figure 1 is an elevation ofthe controlling mechanism towhich my improvement is applied; Fig. 2 is an enlarged verticallongitudinal section thereof, and Fig. 3 is a section at right angles toFig. 2.

A is the controlling lever, which is fulcrumed at B, and extendsadjacent to "a fixed segment C. This segment is provided on its underside with a series of notches D, and

preferably passes through, a slot ii ever.

The locking mechanism for this lever comprises a member F, which isarranged at one side of the lever E,

the slot E for the passage of the segment C. At the lowr end of the slotG, the member F is preferably slightly bev eled to-form a ratchet toothH for engage IIlBIil': with the notches D in the segment, this portionbeing preferably hardened. Above and below the slotG are the slots I andJ, through which are passed securing bolts'K andL for holding the memberF to the lever,

limited lon itudinal adjustment thereof. Above the s ot I is a portion Mwhich is bored to form a recess N exin the tending from the upper end ofthe member F into the slot 1. Within this recess is slida'bly arranged apin 0, andabove this pin a spring I, which at its uptger end abutsagainst the lower end of a rod secured to the member F preferably bythreaded engagement there .with. The rod Q extends, parallel, to thelever, and at its upper end is c'onnectedto a bell crank R, formmg anoperating handle for the latch. I In operation, the tension of thespring P will cause it to press oppositely upon. the pin Q, The' pinwill thus be ment.

. stop on said lever and is slotted at G for passing through forced,downward until it bears against the bolt K in the slot I, which permitsa fixed stop, preventingfurther movement of the pin. On the other hand,the upward pressure of the spring bearing against the rod Q, will forcethis rod upward, carrying with it the member F, which slides. upon thebolts K and L, and forcing the tooth H into engagement with one of thenotches D in the segment C, thus locking the lever from move- The leveris released by grasping the bell crank R, which is adjacent of thelever, this causing the downward movement of the rod Q, and member F compressing the spring P and disengaging the tooth H from the notch D. i

It will be observed that and pin 0 are concealed from view, and that theWhole construction is an exceedingly simple and effective one;

What I claim as my invention is:

1. The combination with a leverand a segment therefor, of a memberhaving a recess therein embracing said segment and slidably secured tosaid lever, a pin slidably located in the recess in said member, aspring within said recess bearing against said pin, a against which saidpin rests wherebythe tension of said spring will to the handle both thespring force said member into locking engagement with said segment, andmeans for moving said member oppositely against the tension of saidspring to disengage it from said seg- 'ment.

2. The combination. with a lever and a seg ment therefor notched on itsunder side, of a memberhaving a longitudinal slot therein embracingsaidsegment and having a tooth for engaging the notches, a bolt passingthrough the longitudinal slot in said member for slidably holding'thelatter to said lever, a

pin in said longitudinal slot bearing against said bolt, a springbearing on said member for forcing said tooth into engagement segment,and means for moving said member against the tension of said spring todisengage the tooth from the notch in the segment.

3. The combination with a lever, having a transverse slot therein of asegment notched on its under side passing thro ugh the transverse slotin said lever, a member adjacent to said lever having a registering slotthrough which the segment passes, a bolt a longitudinal slot in saidbetween said pin and a with the notchand direction against the tensionof I 'ment notched on its under side, of ber 'F slotted at G-for themember whereby the latter is force member and through said'lever forslidably securing the former to the latter, a concealed pin in a recessin'said member which opens into said longitudinal slot, a springconcealed .in said recess bearing against said pin andat its oppositeend against the bearin on said upward into engagement with a notch onthe under side of said se ent, and a rod connected to said member ormoving it in the opposite said spring. 4. The combination with a leverand a segthemempassage therethrough of said mitclied segment, and having a tooth H at the lower end of said slot for enga ing a notch in saidsegment, said member a 0 having a longitudinal slot and a recess, thebolt K passing through the longitudinal slot and securing the member Fto said lever, a in 0 located in the recess, the rod Q secured to saidmember. having said recess and the'spring P in said recess between saidrod and pin, substantially as and for the purpose described.

In testimony whereof I afiix my signature in presence of two witnesses,
